I am going to convert my Coleman combo vac Push Button Keyboard to two switches, one that says vacuum and one that says shampoo. I have a schematic to do this and also bought two push button switches (same as on shampooer handle). I am going to cut out the rectangle where the PBC is ann already had some stainless cut to size to fit in this area. My biggest concern is getting a decal to cover this so it doesn't look mickey moused. If anyone has done this and has any tips, it would be greatly appreciated.
